We should have a look at the jboss mailing lists. JBoss' class loader is called UnifiedClassLoader. The last time I look at UnifiedClassLoaders about a year ago, it seemed very smart. I'd have to look at the details again.

Well, if you your app is seeing jboss/lib/log4j.jar in preference to WEB-INF/lib/log4j.jar, then there is a bug in JBoss. The Servlet spec states that (contrary to the normal Java2 classloading scheme) classes and libraries in WEB-INF/classes and WEB-INF/lib are checked first for classloading and if the classes are not found there, only then does it look to a higher classloader to attempt to load the classes.
I know JBoss has some concept of a single classloader across the whole server (I think that is what I read), but if it doesn't allow for a separate WebappClassLoader, then I think it is a spec compliance violation. What does the JBoss group have to say about this? Putting log4j.jar in WEB-INF/lib *should* provide a completely separate logging environment from the one JBoss uses.

Thanks for the information. I have gone through the stuff you've written.
Here's what I'm doing: 1. I placed log4j-1.2.8.jar in WEB-INF/lib 2. I placed log4j.properties in WEB-INF/classes 3. I deployed the application on JBoss 3.2.1
By default, JBoss has log4j.jar in jboss/lib which is in my classpath.
So, even my application class loader takes the classes from log4j.jar located in jboss/lib?
If I remove log4j.jar in jboss/lib, then I think I will not get server log of JBoss.
How to solve this issue? Please inform.

Hi Sriram,
Do you have log4j.jar in WEB-INF/lib? If not, I'd expect default
initialization not to work. Remember that the webapp class loader can see
parent class loaders, but the parents cannot see the webapp class loader,
hence your log4j.properties will definitely not be found. If you are
trying to use log4j.jar in a parent class loader and want your own
configuration file to be used in your own logging space, then you will need
to use a repository selector. See the log4j-sandbox for working
examples. I wrote something up about this stuff here... http://nagoya.apache.org/wiki/apachewiki.cgi?Log4JProjectPages/AppContainerLogging
